OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 662,051, dated November 20, 1900.

Application filed April 9, 1900. Serial No. 12,136. 1N0 model.)

To all whom, it may concern.-

Be it known that I, MONTGOMERY J. ZAHNI- SER, a citizen of the United States, residing at IVashington, in the county of Washington and State of Pennsylvania, have invented cer tain new and useful Improvements in Oil- Cups; and I do hereby declare the following to be a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in oil-cups or lnbricators for machinery.

The invention relates more particularly to the cover and to means for securing the same in place and to preventits becoming loosened or disengaged on account of the vibrations to which it may be subjected.

Generally speaking, the invention consists of the usual oil or grease cup, cylindrical in shape, with an open top and a screw-threaded hollow stem for attachment to the machinery to be lubricated. The cap or cover is diskshaped, of slightly greater diameter than the cup, and is attached thereto by a screwthreaded depending portion engaging with threads formed upon the inside of the cup. When in place and fully screwed down, aportion of the cover will project beyond the sides of the cup. This portion gives apurchase in adjusting the cup and serves as aplace of engagement for the locking-piece. The locking-piece is cam-shaped, pivoted to a fixed pin from the side of the cup, and engages with the lower projecting face of the cover. A spring keeps the cam in engagement with the cover. The cam is so proportioned and arranged as to afford no resistance to the application of the cover, but will engage and firmly lock it upon any attempt at removal being made. To allow the cover to be removed, a depending finger-piece is provided, by means of which the cam may be disengaged. Stops are provided to limitthe exof the cover.

the cup and cover, and Fig. at is a side view of the complete cup.

In all the several views like parts are designated by identical letters of reference.

The cup is formed of a cylindrical body portion A, with a hollow screw-threaded stein B for attachment to the machinery. The diskshaped cover D is provided with a screwthreaded depending flange D, which engages with corresponding threads cut in the upper portion of the inner face of the cup. A portion D of the cover overhangs the lockinglever. This portion may be milled to allow more facile adjustment. A portion of one of the sides of the cup is cut away at O for the attachment of the locking-piece a and to prevent the locking-piece projecting far beyond the plane of the outside of the cup. This latter is eccentrically pivoted upon the bolt g, secured by screw-threads within the side of the cup. A cam portion a of the looking piece engages with the overhanging part D of the cover and allows the latter to be turned in the direction of the arrow, Fig. 4:, but not the other way unless released. A depending portion provided with a finger-piece a is provided, by means of which the locking-piece may be disengaged from the cover. To assist the gripping action of the locking-piece,

a spring I) is provided, concentrically sur-.

rounding the bolt 9 and engaging with the locking-piece and the cup.

e e are stops to limit the movement of the locking-piece.

g is a lock-nut for the bolt g.

The cover is attached by engaging the screwthreaded part D with the cup and turning it in the direction of the arrow until closely in engagement with the cup, the locking-piece a imposing no resistance. This piece by its eccentric action will effectually prevent the cover being removed by vibration or accident. To remove the cover, the finger-piece a must first be depressed and retained in such depressed position until the cover is removed.

Having now described and ascertained the nature of my invention, what I claim, and desire to secure by Letters Patent, is-

1. In an oil-cup the screw-threaded bodyA thereof, a cam-lever a pivoted thereon, the cover D, screw -threads thereon, the overhanging portion D engaging with the camlever, substantially as described.

2. In an oil-cup the screw-threaded body A thereof, a camdever a pivoted thereon, the cover D, screw-threads thereon, the overhanging portion D engaging with the earnle'ver and a spring I) for engaging the lever, substantially as described.

3. In an oil-cup the screw-threaded body A thereof, a cam-lever a pivoted thereon, the cover D, screw-threads thereon, the overhanging portion D engaging with the camlever, a spring I) for engaging the lever and a finger-piece a for releasing the lever, substantially as described.

4. In an oil-cup theinternallyeserew-threaded body A thereof, a earn-lever a pivoted thereon, the cover D, the depending screwthreaded flange D, thereon, the overhanging portion D engaging with the Cain-lever, substantial] y as described.

5. In an oil-cup, the ir1ternally-threaded body A, the cut-away portion 0, the bolt g thereon, the oaln-levera,supported thereby, the cover D, the depending screw-threaded flange D thereon, the portion D overhanging said cut-away portion, and engaging with the cam-lever, substantially as described.

6. In an oil-cup, the internally-threaded body A, the cut-away portion 0, the bolt 9 thereon, the cain-1ever a, supported thereby, the cover D, the depending screw-threaded 'fiange D thereon, the portion D overhang- MONTGOMERY J. ZAHINISERL Witnesses:
